Robert Pattinson has walked out on Kristen Stewart clearly unable to deal with the embarrassment of being cheated on.

The “devastated” Twilight star has packed up his stuff and left the Los Angeles home he shared with Kristen after her admission she had an affair with her Snow White and the Huntsman director Rupert Sanders, 41.

People magazine reports that Kristen’s groveling apology and acclamations about how much she loves her boyfriend of four years have fallen on deaf ears and Robert is not going to forgive her.

Robert, 26, is reportedly hiding away and is not in contact with Kristen, 22, because he is so “heartbroken and angry.”

As Breaking Celebrity News previously reported, Kristen is writing a letter of apology to Sanders’ wife Liberty Ross to beg for forgiveness for having illicit liaisons with her husband with whom she has two children.

“Kristen didn’t feel it was appropriate to issue a public apology once the story of her affair with Rupert broke,” a source told Breaking Celebrity News.
